For the given circuit, comment on the type of transformer used :

For the given circuit, comment on the type of transformer used :

For the given circuit, comment on the type of transformer used :

Options

  1. AAuxilliary transformer
  2. BAuto transformer
  3. CStep-up transformer
  4. DStep down transformer

Correct answer

C. Step-up transformer

Step-by-step solution

VS=Pi=600.11=545.45{V}_{S} = \dfrac{P}{i} = \dfrac{60}{0 . 11} = 545 . 45

VP=220{V}_{P} = 220

VS>VP{V}_{S} > {V}_{P}

⇒⇒ Step up transformer
